I've noticed, somewhat perplexingly, why are proof coins worth more separately than when packaged together. Case in point according to ''red book''. The face value price of a 1986 proof set is .91 . U.S. mint cost at time of mintage was 7.00$ The gross summary of the proof coins sold individually is close to 26.00 bucks,(assuming pf65) again according to red book, however sold as a package (with original government packaging) and it retails for 7.50$....Now there is a discrepancy with the red book declared value, set at 1.82.....also all the sets I have seen did not include a dollar valued coin. We are dealing with a .50 cent halve pf, a quarter dollar pf, A dime pf,a nickle pf, and a penny pf. To be clear.
